Use of pepper plant leavesâ aqueous extract in the synthesis of silver nanoparticles and the treatment of some pathogenic microorganisms

Abstract

One of the biological techniques which can be used to create nanoparticles is the green synthesis method. The silver nitrate and the extract of the pepper leaf are employed to create silver nanoparticles. The scanning electron microscope (FE-SEM) revealed that there are findings of silver nanoparticles with diameters ranging from (23 nm) to (73 nm). X-ray diffraction analysis confirmed that a spectrum was identical to the spectrum of silver nanoparticles. The study of the ultraviolet-visible spectrum verified the existence of silver nanoparticles as well. The location of the silver surface plasmon (426 nm) has been observed carefully. Silver nanoparticles have been used to kill a variety of bacteria due to their high efficacy in doing so. This process indicates that when the aqueous extract of the pepper plant coupled with silver nanoparticles turned out to be very successful and might be utilized as an antibiotic.
